IMPROVEMENT IN HINGES.

Specification forming part of Letters Patent No. 130,369, dated August 13, 1872.

Specification describing a certain Improvement in Hinges, invented by HENRY HAY- WARD, of Paterson, in the county of Passaic, State of New Jersey.

The following is a description of what I consider the best means of carrying out the invention:

The accompanying drawing forms a part of this-specification.

Figure 1 is a side view of the hinge in the open position. Fig. 2 is a plan view of the same. Fig. 3 is an edge view of the hinge in the closed position. Fig. 4 is a side view of the same. Figs. la and 1b represent an attachment which is applied to produce a higher degree of perfection in the construction and workin g. The position of this attachment is indicated in dotted lines in Fig. 1. Fig. 1a is a central vertical section. Fig. 11) is a perspective view.

This invention consists in furnishing the slotted-eyed removable hinge with double inclines, the one serving to close the door, and the other to hold it when open, and with a removable cap to rest upon its upper part.

Similar letters indicate like parts in all the figures.

Designating the two parts generally by the single letters A and B, I will indicate certain portions of each by the marks A1, B &c. If the addition C be considered as a part of the hinge, to which it is not essential, although it contributes to its perfection, the hinge may be said to be formed of three separate pieces.

B1is a hollow cylindrical portion of sufcient size to receive the lower end of the bolt A2. Its upper edge is a double incline, as indicated by b b. The weight of the door induces a strong bearing of the lower edge of the neck A1 upon this upper edge of the hollow cylinder B. The double incline induces the door to swing either into the shut or open position. The main incline b induces a motion toward the shut position 5 the shorter incline b induces a motion toward the open position. The main function of this latter incline b is to induce the door to remain open rmly when in the open position. The top piece G is important in several relations. It increases the strength of the .upper part B1 by covering the open side or again after the parts have been lubricated.

` I attach much importance to the fact that the bottom of the hollow cylindrical part B1 is closed instead oi' being open directly through. Its-being closed insures the retention of oil when it is applied, and the rising and sinking motion of the parts upon each other insures its distribution upon the wearing-surfaces above. I am aware that hinges have been made before which would incline the door in one direction only. I do not claim such, neither do I claim any form of hinge cited in the references in this case.

I claim as my invention- 1. A hinge with a vertically-slotted eye capable of engagement and disengagement, and formed with double inclines b b/ the one serving to close the door, and the other to hold it Witnesses WM. C. DEY, ARNOLD HOERMANN.
